IPC: C02F1/28
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To provide a water purifying device constituted to prevent the clogging of an inflow port while the entire part is integrated compact and to evenly rotate the inflow water over the entire circumference of a filter cartridge. SOLUTION: A housing space 5 formed in a vessel body is formed to a square section. The filter cartridge 3 constituted to a cylindrical shape is concentrically housed in this housing space 5. The inflow port 8 is opened at the corner of the housing space 5 and an outflow port 15 is opened at the center of the base. A relatively large gap is opened at the front surface of the inflow port 8 and, therefore, even if slightly large foreign matter is mingled in the inflowing water, this foreign matter falls down by coming into contact with the outer peripheral surface of the filter cartridge 3 and the possibility that the inflow port 8 is clogged is eliminated. The flow of the inflow water in one direction around the filter cartridge 3 is made possible. The water is thus passed to the inner side evenly from the entire circumference of the filter cartridge 3.
